In 1997, the DVD format was introduced with a hidden mechanism designed to control the global flow of movies, creating invisible borders where none existed before. This mechanism, known as region coding, was a digital rights management technique that allowed rights holders to dictate where a DVD could be played, when it could be released, and at what price. The American DVD Copy Control Association mandated that all DVD player manufacturers incorporate the Regional Playback Control system, ensuring that a disc encoded for one region would not play on a player from another. This system was not merely a technical specification but a strategic tool for the film industry to maintain control over international distribution. The result was a world where a movie released in the United States could not be played in Europe, even if the physical disc was identical, simply because of a code embedded in the disc's data. This invisible wall was designed to prevent the free movement of goods, allowing studios to charge different prices in different countries and to stagger release dates to maximize profits. The technology was so effective that it became a standard practice, embedding itself into the very fabric of home entertainment. However, the system was not without its flaws, and soon, consumers and manufacturers began to find ways to bypass these restrictions, leading to a cat-and-mouse game that would define the early years of the DVD era.
The Seven Regions
The world was divided into eight distinct regions, each with its own set of rules and restrictions, creating a complex patchwork of compatibility. Region 1 covered the United States, Canada, and Bermuda, while Region 2 included Europe, Japan, and the Middle East. Region 3 encompassed Southeast Asia, South Korea, and Taiwan, and Region 4 covered Latin America and Oceania. Region 5 included Russia, China, and parts of Africa, while Region 6 was reserved for mainland China. Region 7 was designated for MPA-related DVDs and media copies in Asia, and Region 8 was for international venues like aircraft and cruise ships. These regions were not arbitrary; they were carefully mapped to align with existing television standards and market strategies. For example, Region 2 included countries that used the PAL television format, while Region 1 used NTSC. This alignment was not a coincidence but a deliberate choice to ensure that the region codes would work seamlessly with the existing infrastructure of home entertainment. The system was so intricate that some discs were encoded with multiple region codes, allowing them to be played in several regions. This flexibility was a response to the growing demand for region-free playback, but it also highlighted the complexity of the system. The regions were not static; they evolved over time, with some countries changing their region codes to align with new market realities. For instance, the Baltic states switched from Region 5 to Region 2 due to EU single market laws, while Mexico and other Latin American countries adopted both Region 1 and Region 4 codes. The system was a testament to the film industry's ability to adapt and control the global market, even in the face of technological and legal challenges.
In a desperate attempt to maintain control, the film industry introduced a retroactive measure known as Region-Code Enhancement, or RCE, which was designed to defeat region-free players. This scheme was deployed on only a handful of discs, but its impact was profound. The disc contained the main program material region-coded as Region 1, but it also included a short video loop of a map of the world, which was coded as Region 2, 3, 4, 5, and 6. The intention was that when the disc was played in a non-Region 1 player, the player would default to playing the material for its native region, which was the aforementioned video loop. This loop was impossible to escape from, as the user controls were disabled, trapping the viewer in a never-ending display of a world map. The scheme was fundamentally flawed, as region-free players tried to play a disc using the last region that worked with the previously inserted disc. If it could not play the disc, it would try another region until one was found that worked. RCE could be defeated by briefly playing a normal Region 1 disc and then inserting the RCE-protected Region 1 disc, which would now play. The system also caused problems with genuine Region 1 players, leading to a backlash from consumers and manufacturers. Many multi-region DVD players defeated regional lockout and RCE by automatically identifying and matching a disc's region code or allowing the user to manually select a particular region. Some manufacturers of DVD players now freely supply information on how to disable regional lockout, and on some recent models, it appears to be disabled by default. The RCE scheme was a clear indication of the film industry's determination to maintain control, even in the face of technological and consumer resistance.
The Format War
The DVD format was not the only player in the game; it was part of a larger battle over television standards and regional compatibility. DVDs were formatted for use on two distinct regional television systems: 480i/60 Hz and 576i/50 Hz, known as NTSC and PAL/SECAM respectively. NTSC was the analog TV format historically associated with the United States, Canada, Japan, South Korea, Mexico, Philippines, Taiwan, and other countries, while PAL was the analog color TV format historically associated with most of Europe, most of Africa, China, India, Australia, New Zealand, Israel, North Korea, and other countries. Brazil adopted the variant PAL-M, which uses the refresh rate and resolution commonly associated with NTSC. SECAM, a format associated with French-speaking Europe, while using the same resolution and refresh rate as PAL, is a distinct format which uses a very different system of color encoding. Some DVD players can only play discs identified as NTSC, PAL, or SECAM, while others can play multiple standards. In general, it is easier for consumers in PAL/SECAM countries to view NTSC DVDs than vice versa. Almost all DVD players sold in PAL/SECAM countries are capable of playing both kinds of discs, and most modern PAL TVs can handle the converted signal. NTSC discs may be output from a PAL DVD player in three different ways: using a non-chroma encoded format such as RGB SCART or YPBPR component video, using PAL 60 encoded composite video/S-Video, or using NTSC encoded composite video/S-Video. However, most NTSC players cannot play PAL discs, and most NTSC TVs do not accept 576i video signals as used on PAL/SECAM DVDs. Those in NTSC countries, such as the United States, generally require both a region-free, multi-standard player and a multi-standard television to view PAL discs, or a converter box, whereas those in PAL countries generally require only a region-free player to view NTSC discs. The format war was a significant challenge for consumers, who had to navigate a complex landscape of compatibility issues to enjoy their favorite movies.
The Unlocking Code
The region coding system was not impenetrable; it was vulnerable to a variety of unlocking methods that allowed consumers to bypass the restrictions. Standalone DVD players usually had a configuration flag set in each player's firmware at the factory, which held the region number that the machine was allowed to play. Region-free players were DVD players shipped without the ability to enforce regional lockout, usually by means of a chip that ignored any region coding, or without this flag set. However, if the player was not region-free, it could often be unlocked with an unlock code entered via the remote control. This code simply allowed the user to change the factory-set configuration flag to another region, or to the special region 0. Once unlocked this way, the DVD player allowed the owner to watch DVDs from any region. Many websites existed on the Internet offering these codes, often known informally as hacks. Many websites provided instructions for different models of standalone DVD players, to hack, and their factory codes. Computer DVD drives also had region coding, with older drives using RPC-1 firmware, which meant the drive allowed DVDs from any region to play, and newer drives using RPC-2 firmware, which enforced the DVD region coding at the hardware level. These drives could often be reflashed or hacked with RPC-1 firmware, effectively making the drive region-free. This may void the drive's warranty. Some drives may come set as region-free, so the user was expected to assign their region when they bought it. In this case, some DVD programs may prompt the user to select a region, while others may actually assign the region automatically based on the locale set in the operating system. In most computer drives, users were allowed to change the region code up to five times. If the number of allowances reached zero, the region last used would be permanent even if the drive was transferred to another computer. This limit was built into the drive's controller software, called firmware. Resetting the firmware count could be done with first- or third-party software tools, or by reflashing to RPC-1 firmware. The unlocking code was a testament to the ingenuity of consumers and manufacturers, who found ways to circumvent the restrictions imposed by the film industry.
The Legal Battle
Region coding was not without its critics; it was a subject of intense legal and ethical debate. Region coding was criticized for facilitating unlawful market control strategies, such as price fixing. The sale of region-coded DVDs was illegal in New Zealand, and the Australian Competition & Consumer Commission warned that DVD players that enforce region-coding may violate the Competition and Consumer Act 2010. The ACCC advised consumers to exercise caution when purchasing a DVD video player because of the restrictions that limit their ability to play imported DVDs. The report stated that these restrictions were artificially imposed by a group of multinational film entertainment companies and were not caused by the existing differences in television display formats such as PAL, NTSC, and SECAM. The ACCC was currently investigating whether Australian consumers were paying higher prices for DVDs because of the ability of copyright owners, such as film companies, to prevent competition by restricting imports from countries where the same authorized video titles were sold more cheaply. In 2012, a report from the Sydney Morning Herald revealed that region-free DVD players were legal in Australia, as they were exempt from the Technological Protection Measures included in the US Free Trade Agreement. Under New Zealand copyright law, DVD region codes and the mechanisms in DVD players to enforce them had no legal protection. The European Commission also criticized the practice, investigating whether the resulting price discrimination amounted to a violation of European competition law. The Washington Post highlighted how DVD region-coding was a major inconvenience for travelers who had the desire to legally purchase DVDs worldwide and return with them to their countries of origin, students of foreign languages, immigrants who wanted to watch films from their country of origin, and foreign film fans. Another criticism was that region-coding allowed for local censorship, such as the Region 1 DVD of the 1999 drama film Eyes Wide Shut, which contained the digital manipulations needed for the film to secure an MPAA R-rating, while these manipulations were not evident in discs that were not in Region 1. The legal battle was a significant challenge for the film industry, which had to navigate a complex landscape of consumer rights and market regulations.
The Next Generation
As the DVD format began to decline, the film industry moved on to the next generation of optical media, with Blu-ray discs introducing a new region coding system. Blu-ray discs used a much simpler region-code system than DVD, with only three regions, labeled A, B, and C. Region A covered the Americas and their dependencies, Taiwan, Japan, Hong Kong, Macau, Korea, and Southeast Asia. Region B included Africa, West Asia, most of Europe, Australia, New Zealand, and their dependencies. Region C covered Central Asia, China, Mongolia, South Asia, Belarus, Ukraine, Russia, Kazakhstan, Moldova, and their dependencies. Unlike DVD region codes, Blu-ray regions were verified only by the player software, not by the computer system or the drive. The region code was stored in a file or the registry, and there were hacks to reset the region counter of the player software. In standalone Blu-ray players, the region code was part of and enforced by the firmware. Similar to DVDs, some Blu-ray rippers, such as AnyDVD HD, could remove region codes as well as other types of digital rights management, including Advanced Access Content System and BD+. Multi-regional standalone players were available, and some standalone Blu-ray players could be modified to be region-free. A new form of Blu-ray region coding tested not only the region of the player/player software, but also its country code. This meant that while both the US and Japan were Region A, some American discs were not going to be played on devices/software installed in Japan or vice versa, due to the two countries having different country codes. The United States had 21843 or Hex 5553, Japan had 19024, or Hex 4a50, and Canada had 17217 or Hex 4341. Although there were only three Blu-ray regions, the country code allowed much more precise control of the regional distribution of Blu-ray discs than the six or eight DVD regions. In Blu-ray discs, there were not any special regions like the regions 7 and 8 in DVDs. Ultra HD Blu-ray discs were region-free as they were generally encoded as worldwide region. The next generation of optical media was a testament to the film industry's ability to adapt and control the global market, even in the face of technological and legal challenges.
